 ## Customization
 
 Pigsty is highly customizable, You can describe the entire database and infra deployment with **300+** [**parameters**](https://pigsty.io/docs/reference/param/) in a single config file and materialize them with one command.
-There are many built-in configuration [templates](https://pigsty.io/docs/conf) that can be used directly.
